Silver circular Craft above hay field

Circular craft seen maybe about the size of a small car near Inverness, Culloden Moor with what appeared to be 3 circles on the surface equally spaced could have been lights cannot remember clearly.  Very silver and shiny metal surface.  I would only have been about 9 years old. I drew a picture and it was given to the police at the time by my parents.  I was passing in a school bus and saw it very low (maybe a few feet about the ground level) and stationary above a field where the hay had been cut.  I cannot remember very clearly as I was so young and wondered if others had seen it.  I remember trying to tell a friend on the bus to look but couldn't attract their attention quickly enough.
Date is approximate.  PD
